i don't really think number one is that big a deal. would i do it for 2 grand? probably. i guess i'd feel dirty after, but i wouldn't feel too weird about it. i'm sure after a beer and sex with my girlfriend i'd be over it.
making out is a totally different story. i wouldn't do it for 10 grand i don't think, but 20 grand? i dunno, maybe. i'd have to think about it.
the whole anal thing is a totally different story. i at least know what it feels like to make out with a girl, as gross as it makes me feel to think about it, making out with a guy can't be that much different. getting a dick in my ass is just scary and terrifying, i'd need a shitload of money to even start thinking about that one.
